Comprehensive Analysis Of 2mm Grey Smooth-Surfaced Multi-Purpose Chipboard (70×100cm)

2. Core Parameter Analysis​

1. Thickness: 2mm - Core Advantage of Thin Design​

Physical Properties: As a thin chipboard, the 2mm thickness is much lower than that of conventional chipboards (common thickness: 3-25mm). It is lightweight, weighing approximately 1.6-1.8kg per square meter (compared to about 4kg for a conventional 5mm chipboard). It also has better flexibility than thicker boards, allowing slight bending with a bending radius of around 50-80cm to prevent breakage.​

Application Logic: It is suitable for scenarios with strict requirements on board thickness and weight, such as thin packaging boxes and decorative backing boards. There is no need for secondary sanding to reduce thickness, which directly lowers processing costs.​

2. Size: 70×100cm - Balancing Versatility and Flexibility​

Specification Advantages: It belongs to a medium-small size category. A single sheet is easy to carry, weighing about 1.12-1.26kg, which can be held by one person. It can be easily cut into smaller sizes (e.g., 30×40cm for storage box side panels, 10×70cm for decorative strips) using cutting tools like utility knives or electric saws.​

Scenario Adaptation: It avoids the cutting waste associated with large-sized boards (e.g., 122×244cm) and is suitable for small-batch DIY projects, small-scale packaging, and desktop ornaments. A single sheet can meet the needs of most small-scale projects.​

3. Surface: Smooth-Surfaced​

Process Implementation: The surface undergoes "fine sanding + grey coating" treatment, with a roughness of Ra ≤ 1.6μm (no granular feel when touched by hand). The coating is mostly water-based environmentally friendly paint or melamine-impregnated paper, which has strong adhesion (meeting the requirement of "surface bonding strength ≥ 0.7MPa" in the GB/T 4897-2015 Chipboard Standard).​

Core Value: There is no need for additional painting or veneering. It directly presents a grey matte or glossy finish and has better stain resistance than ordinary chipboards (stains can be wiped off with a damp cloth and are not easy to penetrate).​

4. Color: Grey - Combining Versatility and Practicality​

Tone Characteristics: It is mostly medium grey (around Pantone 19-4020TPX) with no obvious color difference. It is suitable for modern minimalist, industrial, and other design styles and can be matched with colors such as black, white, and wood tones.​

Scenario Advantages: It avoids the problem of white being easy to get dirty and dark colors absorbing heat. It is suitable for scenarios that require color dirt resistance and aesthetics, such as interior decoration, packaging appearance, and display props.​

5. Function: Multi-Purpose​

Core Support: Although the board is thin, its physical properties meet the standards (flexural strength ≥ 12MPa, elastic modulus ≥ 1500MPa, complying with the "dry condition use" level requirement in GB/T 4897-2015). It can meet three core needs: "load-bearing, decoration, and isolation."​

3. Material and Process Characteristics​

1. Base Material: Core Advantages of Chipboard​

Raw Material Composition: It mainly uses fast-growing wood scraps (such as pine and poplar). Its environmental protection can be certified by "E0 grade" and "E1 grade" (formaldehyde emission ≤ 0.124mg/m³, suitable for indoor use).​

Structural Features: It has a three-layer or multi-layer structure (fine material on the surface + coarse material in the core). The fine surface material ensures surface smoothness, while the coarse core material balances strength and weight to prevent the thin board from being too brittle.​

4. Typical Application Scenarios​

1. Packaging Industry: Lightweight Buffering and Appearance Carrier​

Thin Packaging Boxes: Such as liners for electronic product (earphones, watches) packaging boxes and partitions for cosmetic gift boxes. The 2mm thickness can provide moderate buffering, and the grey surface enhances the texture.​

Transportation Protection: Used as a spacing backing board for fragile items (glass, ceramics). It is lightweight and foldable, reducing transportation costs.​

2. Home and DIY Field: Easy-to-Process Decorative Parts​

Furniture Accessories: Drawer partitions, wardrobe dust-proof boards, and desktop ornament bases. They can be used directly after cutting without additional treatment.​

DIY Handicrafts: Handmade photo album covers, storage box shells, and wall decorative pendants. They can be assembled with glue and screws, suitable for beginners.​

3. Commercial Display: Low-Cost Props​

Shelf Liners: Layered liners for shelves of small commodities (jewelry, stationery). The grey surface highlights the color of the commodities.​

Temporary Display Racks: Simple display boards and price tags for exhibitions and promotional activities. They are lightweight and easy to install, and can be recycled after use.​

4. Industrial Auxiliary: Functional Partitions​

Electronic Equipment Liners: Internal partitions for small electrical appliances (routers, printers). They isolate components without increasing the weight of the equipment.​

Model Making: Wall and floor components for architectural models and industrial models. They are easy to cut and have a flat surface, suitable for fine modeling.​

5. Purchasing and Usage Guidelines​

1. Key Purchasing Indicators​

Environmental Grade: Priority should be given to E1 grade or above, especially for indoor use or scenarios involving contact with the human body (e.g., children's handicrafts).​

Surface Quality: Check for scratches, color differences, and bubbles. Strong light can be used to observe the surface flatness.​

Edge Integrity: The edges of thin boards are prone to damage. It is necessary to ensure that there is no cracking or chipping at the edges (which affects subsequent splicing).​

2. Usage Precautions​

Moisture Resistance: The chipboard base material has strong water absorption. Avoid long-term contact with water or placement in humid environments (e.g., bathrooms). If used in humid scenarios, a moisture-proof agent should be applied to the surface.​

Load-Bearing Limit: The 2mm board has a limited load-bearing capacity (single-point load-bearing ≤ 5kg, uniform load-bearing ≤ 10kg/㎡). It cannot be used for bearing heavy objects (e.g., bookshelf partitions).​

Processing Tools: For cutting, utility knives (break after multiple cuts) or jigsaws (for fine shapes) can be used. For drilling, small-diameter drill bits (≤ 3mm) should be used to avoid edge cracking.​

7. Conclusion​

The 2mm grey smooth-surfaced multi-purpose chipboard (70×100cm) takes "thin design, easy processability, and multi-functionality" as its core competitiveness. It balances cost, performance, and scenario adaptability. It not only meets the lightweight needs of professional fields (such as packaging and display) but also is suitable for DIY creations by ordinary users. During use, attention should be paid to moisture protection and load-bearing limits. Maximizing its value can be achieved by matching it with appropriate scenarios.
